All but one of the hydraulic fracturing companies that received voluntary information requests in September have agreed to submit timely and complete information to help the U.S. Environmental Protection Agency conduct its study on hydraulic fracturing.

Halliburton is the only one that failed to provide EPA the information necessary to move forward with the study so the agency issued a subpoena for the information. One week after EPA announced the subpoena, Halliburton announced a new microsite that, among other things, discloses some information about the identity and common uses of the additives and constituents generally involved in the hydraulic fracturing process.

EPA’s congressionally mandated hydraulic fracturing study will look at the potential adverse impact of the practice on drinking water and public health. The agency is under a tight deadline to provide initial results by the end of 2012 and, according to the agency; the thoroughness of the study depends on timely access to detailed information about the methods used for fracturing.

EPA announced in March that it would conduct this study and solicit input from the public through a series of public meetings in major oil and gas production regions. The agency has completed the public meetings and thousands of Americans from across the country shared their views on the study and expressed full support for this effort.

On Sept. 9, EPA reached out to BJ Services, Complete Production Services, Halliburton, Key Energy Services, Patterson-UTI, RPC, Inc., Schlumberger, Superior Well Services, and Weatherford, seeking information on the chemical composition of fluids used in the hydraulic fracturing process, data on the impacts of the chemicals on human health and the environment, standard operating procedures at their hydraulic fracturing sites and the locations of sites where fracturing has been conducted. Eight of those companies have either fully complied with the request or made unconditional commitments to provide all the information on an expeditious schedule.

The microsite introduces a new fracture fluid system that uses materials sourced from the food industry. The company's new service will use ultraviolet light instead of additives to control bacteria and another system will treat wastewater at the well site so that it can be reused.

“Halliburton has just made available new web pages to emphasize our forthright disclosure of the additives and constituents that are used for several typical wells in Pennsylvania. We believe this effort represents an important and substantive contribution to the broader long-term imperative of transparency,” said David Adams, vice president of Halliburton’s production enhancement product service line.

While the initial focus of the disclosure pages are limited to activities taking place in Pennsylvania, where development of the Marcellus Shale is already well under way, the company is committed to continuing to provide hydraulic fracturing fluid disclosure information for every U.S. state in which Halliburton’s fracture stimulation services are in use, the press release stated.
